2, Claims. (01. zzes) This application is a division of myapplicanow Patent Number 2,314,299, dated March 16,

1943. V This invention relates to filling spouts, particularly those employed in conjunction with weighing-feeder mechanisms for the filling of bags and the like. Intheweighing out ofsmall unit quantities of various bulk commodities such as flour, sugar, salt, beans, candy and thelike, it is essentialflthat the transfer of materials into the container be efiected quickly and without loss g of the materials fed and Weighed. The filling spout of this invention is particularly, suited to suchuse. A i I i It is generally thebroad object of, th present tion Serial No. 296,579, filed septembe zs, 1939,

invention to provide a novel form of filling spout h to enable bulk materials to be fed, weighedand rapidly discharged into suitable containers such as aibag or thelike. The spout of this invention also facilitates the opening and the proper positioning of a container; to receive material from the spout, l

Th invention includes other objects and features of advantage someof which, together with The forward edge IQ of member ll slopes out wardly, away iromthe member proper and be yond the vertical plane represented inFig. 1 by the line I 5-l5, to fit snugly against terminal In addition, member H includes a portion l8 thereof which edge l4 and lip I2 on member 9;

extends outwardly away from thehinge provided by screws 16 so that member II is biased to engage the terminaledge l4 andthe terminal lip I2 on member 9. This ensures a quick and adequate closure for the down spout and any material therein. In use, an operator engages extension finger ll provided upon the ringy'l to steady the down i i spout-filling spout structurabecause this is usually mounted upon some type of movable weigh ing frame. A bag or other container is then par- 1 tiallyopened and drawn into position. C'onven iently the size ofthe bag employed can be such that it fits snuglyabout members 9 and ll so that when these are moved apart the bag is fully opened and retained in position until such time the foregoing will appear hereinafter wherein the present preferred form is disclosed. e

In the drawing accompanying and forming a parthereof Figure 1 is a side elevation of the filling spout of this invention. t

Figure 2 is a side elevation, partly in section,

taken along the vertical sectionline shown in Figure 1.

A typical down spout of a suitable feeder weighing mechanism is indicated generally at 6. This downspout, usually in the form of a frus tuml of a cone is shown as terminatingin a ter- The downspout 6 is usually made of a light sheet metal and the ring 1 serves to reinforce it. The bag filling spout of this invention is indicated generally at 8. It comprises a first member 9 and a secondmember II. The "first member 9 is secured to the terminal ring 1 and is usually fixed in position. It depends from the terminal'ring 'l with the outer face thereof arcuately formed and flowing smoothly down to a terminal lip at, 12 provided along the lower edge thereof. The inner terminal edge IA of member 9 slants outwardly and away from a vertical plane indicated generally by line iii-l5. The reason for this will become further apparent in connection with the detailed disclosure of of spout of this invention 1 as the material iscompletely fed into the bag.

Or, if desired, the bias provided upon member ll can be such that the material is retained and held until such time. as itj is released by an operator engaging extension l8 on member I I and rocking the member about itshinge. Member.

ll can alsobe biased by meansof a spring toward closed position. Iclaim: t a i 1. In combination, a downspout, a bag filling spout, said bag filling spout comprising afirst I and a second member, saidfirst member bein fixed on said downspout andextending below the terminal end of said downspout, said first memher having its outer depending wall of arcuate section and extending substantially vertically to provide a relatively'thin, flat member with an arcuate terminal lip, the edges of saidlterminal wall extendinginwardly at an angle to a plane passed vertically through an upper portion of member II, which is hinged at its upper end on suitable screws l6 which extend into thering l.

said member to provide said terminal lip at a distance spaced from said vertical plane, said second member being hinged on said downspout and J having an outer depending wall of arcuatesection, the radiiof both said wall'arcuate sections t being relatively great so that said sections when i closed provide cooperatively an element adapted readily to enter and open an end of a paper bag positioned forffillingsaidsecond member being, 7 hinged substantially on said vertical plane and having a substantial portion thereof normally lying on that side of said vertical plane which is adjacent to the first member and'complementary to said first member to provide a closure for said downspout.-

2. In combination, a downspout, a bag filling spout, said bag filling spout comprising a'first and a second member, said first member being fixed on said downspout and extending below the terminal end of said downspout, said first member having its outer depending wall of arcuate section and extending substantially vertically to provide a relatively thin, fiat member with an arcuate terminal lip, the edges'of said terminal wall extending inwardly at an angle to a plane passed vertically through an upper portion of said member to provide said terminal lip at a distance spaced from said vertical plane, said second member being hinged on said downspout and having an outer depending wall of arcuate section, the radii of both said wall arcuate sections being relatively great so that said sections when closed provide cooperatively an element adapted readily to enter and open an end of a paper bag positioned for filling, said second member being hinged substantially on said vertical plane and having a substantial portion thereof normally lying on that sideof said vertical plane which is adjacent to the first member and complementary to said first member to provide a 1 closure for said downspout, said second member having a portion of its outer wall extending upwardly to a point above a horizontal plane passed through said hinge to provide a bias on said 15 second member toward closed position.
